Hi everyone,
I just got G2 a couple of days ago, I like it especially KnockOn feature very much. But I find a problem of it.
It occasionally cannot be unlocked after I turn off the screen(lock the phone) for a while, I need to repeat to knock it for many times and finally the screen lighted.
I think it's not a hardware issue as the KnockOff feature always okay(100%), I searched and found a similar problem of here:http://forums.androidcentral.com/lg-...issue-fix.html
But fix the "Motion sensor calibration" doesn't work for me.

Any suggestion or tips on KnockOn feature, have you got the problem like me? Thanks

What I have noticed is that anywhere works equally well on the screen for me, the trick is you have to hit the same spot for both taps, even a bit off and it doesn't work regardless if it is the top, bottom, or center. I think it's just easier to hit the same spot when you are closer to the edge of the screen and that's why it appears those areas work better.

It seems not true, with a better lag between 2 taps, even a little bit away from the twice tap it works fine.

i would guess if having a problem knock on that you have some app installed that is conflicting with it... some lockscreen app or widget you've chosen? if you cant pinpoint it, i'd wipe the phone clean being a new phone and test thoroughly before starting to reinstall apps. heck, that's how i had to find out why i was getting errors and issue with my lock screen with kitkat and swiftkey.

it doesn't matter where I tap the screen for me. I find it works about 90% of the time if I take the time to deliberately tap it, especially with the phone on a table. if I'm doing it casually while holding it it's probably closer to 75%. like the above poster said, if your second tap is even a little off it won't work.
